如何使用框架在Swift上的循环中设置x位置 [英] How to use frame to set x position in loop on Swift

问题描述

我有一个数组，计数在1到3之间变化. 我想在屏幕中间以一定距离构图 标签的宽度也是固定的

I have an array that count is between 1 to 3 varies. I want to frame them in the middle of the screen with a certain distance Also the width of the labels is fixed

let array = ["some1", "some2", "some3"]

func setLabel(){
  var i = -1
  for text in array{
      i += 1
      let label = UILabel()
      label.fram = CGRect(x: screenWidth/2 - (CGFloat(i)*50) + 25, y: 100, width: 50 , height: 20)
      label.text = text
      addSubview(label)
  }
}

推荐答案

您可以按照 @matt 的建议使用stackview .如果您不想使用stackview，可以像这样通过数组计数和标签索引来计算x位置

You can use stackview as suggested by @matt. If you don't want to use stackview you can calculate the x position by array count and label index like this

let array = ["some1", "some2", "some3"]
func setLabel(){
    var i:CGFloat = 0
    for text in array{
        i += 1
        let label = UILabel()
        label.backgroundColor = .red
        label.frame = CGRect(x: (view.bounds.width/CGFloat(array.count+1))*i-25, y: 100, width: 50 , height: 20)
        label.text = text
        view.addSubview(label)
    }
}
